Display panel, method of manufacturing the same and display device

A method of manufacturing a display panel, wherein the display panel comprises a first bending region capable of being bent along a first direction, a second bending region capable of being bent along a second direction, and a third bending region located between the first bending region and the second bending region, the first direction intersects the second direction, the method comprises:

• fabricating a functional film layer on a substrate, wherein the functional film layer comprises a non-hollowed region located in at least one of the first bending region and the second bending region, and a part of the functional film layer located in the third bending region comprises a plurality of functional via holes spaced from each other,
• wherein the functional film layer comprises a first conductive pattern, the first conductive pattern comprises a plurality of first conductive via holes located in at least one of the first bending region, the second bending region and the third bending region, and
• wherein the functional film layer further comprises:
• a first inorganic layer stacked with the first conductive pattern, the first inorganic layer comprises a plurality of first inorganic via holes located in at least one of the first bending region, the second bending region and the third bending region, and an orthographic projection of each of the plurality of first inorganic via holes on the substrate does not overlap with an orthographic projection of each of the plurality of first conductive via holes on the substrate.
